Sid, the clumsy housekeeper

You know I bought a Service Droid from Dagu, right? I wrote about assembling the kit here: http://letsmakerobots.com/node/39518

What "Brain" should I chose for my robot?

I am considering a more advanced  "brain" for my Service Droid robot. I know I could use the computer to do all the advanced computing and relay commands to the robot, but if possible, I would like to have an integrated system. So far, I see 3 variants:

1. Raspberry Pi + webcam (+ screen?)
2. Android phone with integrated front camera
3. Android tablet (4.3" screen) + OTG adapter + webcam

Review: The Service Droid kit from Dagu

I have received my Service Droid kit along with the Rover 5 robot chassis on a Monday evening. Excited, I opened up the package to reveal 2 big boxes, one with the Rover 5 and the other with the actual SD kit. The base comes assembled, with a battery box, a screwdriver (with a magnetized Phillips end), an Allen key (hex wrench) and a little bag with silicone lubricant. The droid kit comes with lots of parts grouped in separate labeled bags for easier assembly. To do the assembly, I used a cutter, a plier and the screwdriver from the Rover 5 box.

Charger for NiMH packs

Hi guys, anyone can recommend a charger for a 5 or 6 NiMh batteries connected in series? I would like to keep the pack on my robot and be able to just plug in the charger instead of pulling the batteries out and place them in the charger (most AA chargers have only 4 slots, so 2 batteries need to wait to charge or I have to use 2 chargers).

So, any charger for 7.2V or 6V able to charge 2700mAh AA NiMH battery pack?

Thanks!

Toronto Mini Maker Faire

Hi guys, on September 21st and 22nd there will be a Mini Maker Faire in Toronto, Canada.

Is anyone from LMR attending? I would like to meet up and chat. If anyone is interested to set up a LMR booth, we can talk, cause I'm not going to do it alone. On the 22nd is my daughter's birth day, so I will be bussy with her party.

Let me know if you plan to attend!

ArduinoDroid

Finaly, after years of waiting, the killer app is here: ArduinoDroid an app that allows one to program an Arduino board from a tablet or (some) phone. Yeah, now you can pack light for that robotic contest or conference, no need to carry the whole laptop, just a tiny 7" tablet that you can also use to read, watch movies, play games... or quickly tweak your sumo robot's code.

The Social drink Machine

Well, the Romanians at Robofun have built a drink mixing robot. It's not looking like the famous Bar2D2, it's looking more like a 2 axis CNC machine, but it has it's share of coolness. To order a drink, you scan the bar code with your smart phone, get to the site and choose a drink. Then wait for a bar code to be displayed on your phone, place a glass in the machine and show the bar code to the machine's webcam.
